Abstract

Transient hyperthyroidism after neck trauma is not common. The case of a 23-year-old female is presented, who suffered a traffic accident presenting trauma to the neck when hitting with the crank of a motorcycle, subsequently presented suppression of TSH and elevation of circulating T4, with ultrasound and CT that ruled out bruises or ruptures of the gland, which after conservative management presented normalization of thyroid hormones and evolved without sequelae. A review of the literature on thyroiditis and transient hyperthyroidism after neck trauma was conducted.

Key words: Transient hyperthyroidism; Thyroiditis; neck trauma; traffic accident.
